Should be run :) is this for slope?
That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= <span>(7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= </span>7w^3 - 4w + 3 + 5w^3 - 3w - <span>3
= 12w^3 - 7w
= w(</span><span>12w^2 - 7</span>)
The answer is 7x athats it
The answer is is 4.2
3^2+3^2=c^2
9+9=c^2
18=c^2
Square root both sides
4.242640687119285=c
